title: [Prevalence of digestive system cancer patients covered by the Mexican Institute of Social Security of the State of Sinaloa, Mexico].
abstract: OBJECTIVE
  To determine the frequency of malignant neoplasia of the digestive tract in patients seen at the IMSS concentration hospital in Culiacán, Sinaloa, México.
  
  
  METHODS
  From 32,097 histopathologic studies performed at No. 1 Regional General Hospital Pathology Department in Culiacán, Sinaloa, 406 were identified as digestive tract malignant neoplasia (DTMN); patient's age and gender were analyzed as well as involvement site and histological type. Benign and metastasic neoplasias were excluded.
  
  
  RESULTS
  DTMN prevalence: 1.26%; more affected: 60-69 years; male predominance (66%), p < 0.0001. As a whole, 47.2% of the studies reported stomach cancer; colorectal cancer: 17.5%; gall bladder and bile duct cancer; 8.4%; liver cancer: 8.1%; the remainder were located in other sites. DTMN rate by histologic type were similar to other concentration hospitals of the country.
  
  
  CONCLUSIONS
  DTMN has an outstanding magnitude in IMSS Sinaloa patients if other hospital registrations are considered. There are possible regional factors that may contribute to this behavior.
